STS-1 Active Alarm Traps
Trap
If enabled, the unit issues a trap when...
LOS
(Loss of Signal)
The controller card has lost the network receive
signal.
The controller card has lost the network receive
signal.
LOF
(Loss of Framing)
The controller card detects a loss of framing
from the network.
The controller card detects a loss of framing
from the network.
LOMF
(Loss of Multiframe)
The controller card detects loss of H4
multiframe from the network.
The controller card detects loss of H4
multiframe from the network.
AIS-L
(Line Alarm Indication Signal)
The controller card is receiving a line alarm
indication signal. Line AIS defect is detected as
a "111" pattern in bits 6, 7, and 8 of the K2 byte
in five consecutive frames.

AIS-P
(Path Alarm Indication Signal)
The controller card is receiving a path alarm
indication signal. AIS-P is defined as all ones in
bytes H1, H2, and H3 as well as all ones in the
entire STS synchronous payload envelope.

RFI-L
(Line Remote Failure Indication)
The controller card is receiving a line remote
failure indication. RFI-L is declared when the
incoming line remote defect indication (RDI-L,
"110" pattern in bits 6,7, and 8 of the K2 line
overhead byte) last for 2.5 +/- 0.5 seconds.

incoming line remote defect indication (RDI-L,
"110" pattern in bits 6,7, and 8 of the K2 line
overhead byte) last for 2.5 +/- 0.5 seconds.
RFI-P
(Path Remote Failure Indication)
The controller card is receiving a path remote
failure indication. RFI-P is declared when the
incoming path remote defect indication (RDI-P,
"1" in bit 5 of the G1 path overhead byte for 5
contiguous frames) last for 2.5 +/- 0.5 seconds.
